BACKGROUND

A Cyber-attack is a type of offensive maneuver that targets computer systems, infrastructures, computer networks, and/or personal computers devices by various malicious acts that either steals, alters, or destroys a specified target by hacking into a susceptible system. In one example, a hacker/unauthorized user may login to a computer system using valid login credentials. Traditional defensive measures for identifying malicious activity associated with compromised login credentials or insider attacks often are not effective because the unauthorized user is granted access to the computer system via normal channels using valid credentials.

It is with respect to these and other general considerations that embodiments have been made. Although relatively specific problems have been discussed, it should be understood that the embodiments should not be limited to solving the specific problems identified in the background.

DETAILED DESCRIPTION

Various embodiments are described more fully below with reference to the accompanying drawings, which form a part hereof, and which show specific exemplary embodiments. However, embodiments may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the embodiments to those skilled in the art. Embodiments may be practiced as methods, systems or devices. Accordingly, embodiments may take the form of a hardware implementation, a software implementation or an implementation combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.

The present disclosure generally relates to identifying anomalous behavior in one or more systems. Accordingly, embodiments described herein include systems and methods for identifying anomalous behavior in one or more systems. In one example, a system may include a cyber-semantic account management system (C-SAMS). A C-SAMS system may be configured to detect cyber threats (e.g., anomalous behavior) when valid login credentials have been compromised by an unauthorized user. For example, the C-SAMS system may be operable to automatically generate user behavior profiles based on user activity observed in one or more network environments. The user behavior profiles may serve as a model of expected behavior such that any activity that deviates from the model of expected behavior may be identified as anomalous behavior.

FIG. 1 illustrates an operating environment 100 for to identifying anomalous behavior according to one or more embodiments disclosed herein. As shown in FIG. 1, the operating environment 100 may include one or more networks 110, application servers 120, import services 130, a database 140, web services 150, and a graphical user interface (GUI) 160. Although FIG. 1 may be described in relation to a C-SAMS system, the embodiments described relative to FIG. 1 may be used in any system capable of identifying anomalous behavior.

The one or more networks 110 may be any communication network. Such communication networks may include, but are not limited to, satellite networks, mobile wireless networks, computer networks, the Internet, etc. The application servers 120 may include at least one computer program for processing and/or storing raw data. In one example, raw data is any data that can be tracked over a period of time over one or more networks 110 (e.g., behavioral data and/or activity data). Behavioral data may include data that is observable and that represents a repeatable pattern of and entity's activity. Activity data may include data that is observable and that represents entity actions performed over one or more networks, for example. An entity may include a user, an individual, an application, software, a person, a process, a group, etc. In one example, the raw data may include weather data, recorded activities of an entity, data representing lights turning on and off, entry into any system requiring authorization, web service endpoints, mission role data, system transactions, resource access, etc. As such, any raw data communicated via the one or more networks 110 may be processed and/or stored by the application servers 120. In one embodiment, the raw data may be in the form of weblog data, access logs, database tables, XML files, HTML files, etc. In one example, the weblog data may include at least one of IP address information, browsing history, download data, and time information.

The import services 130 may include at least one computer program for receiving the raw data from the application servers 120, generating a behavior profile based on the raw data, receiving comparison data, and determining whether the comparison data deviates from a pattern of behavior defined in the behavior profile. In one embodiment, the behavior profile is generated for an entity and is based on recorded activity for the entity. In this regard, the behavior profile defines a pattern of behavior for the entity. In one example, the behavior profile may be generated from a single entity such that the behavior of other entities is not used when generating the behavior profile. As such, the behavior profile is unique to the entity such that unauthorized access using the entity's credentials may be more easily identified. Furthermore, the behavior profile may be generated using less raw data and may be absent from complex profile dependencies. In another example, the behavior profile may be generated from a group of users. The group of users may share common characteristics such as their role/position, location, duties, etc. The recorded activity for the entity may include attributes such as a timestamp, client information (e.g., Internet Protocol and Domain address information), page request Uniform Resource Locator (URL) (e.g., query string, method and protocol), returned status, returned bytes, public key infrastructure (PKI) status, page referrer URL, common access card information (e.g., First, Last, Middle, Suffix, and Number), login name, encryption information (e.g., protocol, cipher, and bit count), user agent string, etc.

Behavior profiles may be indexed based on the attributes of the recorded activity. For example, the behavior profile may be indexed based on the timestamp. Indexing the behavior profile based on the timestamp may facilitate the construction of patterns of behavior based on hourly activity, daily activity, weekly activity, monthly activity, etc. In another example, the behavior profile may be indexed based on page request URL. Indexing the behavior profile based on the page request URL may facilitate the construction of patterns of behavior based on unique page visits of the entity. In another example, the behavior profile may be indexed based on breaking down encryption information into sub components. Indexing the behavior profile based on encryption attributes (e.g., cipher, protocol and bits) may facilitate the construction of behavior patterns based on browser and client settings. These examples are merely illustrative and the behavior profile may be indexed based on any attributes of the recorded activity.

The behavior profile may be generated using any desirable amount of raw data. For example, the behavior profile may be generated based on a day of raw data, an hour of raw data, a week of raw data, a month of raw data, a year of raw data, etc. In one example, the amount of raw data used to generate the behavior profile may be based on the type of anomalous behavior that is being identified. For example, if suspect criteria may be linked to number based thresholds then raw data can be processed without the need for a minimum sample size. In another example, the amount of raw data used to generate the behavior profile may be based on the content of the data. For example, the content of the data may include the type of activity that has actually been recorded in the raw data. In this regard, the behavior profile may be generated for any date range defined and/or identified by the raw data. The date range used to generate the behavior profile may be a benchmark date range. The benchmark date range may be configurable. The benchmark date range may be based on historical data of a user that has been identified as expected behavior. As such, data based on recent activity of a user (e.g., comparison data) may be compared with the behavior profile having a benchmark date range to identify anomalous behavior.

Generating the behavior profile may include transforming the raw data into one or more relational database objects and constructing the behavior profile using relational algebra. For example, the raw data may be organized into a variety of tables based on the attributes of the entity recorded activity. The behavior profile may be constructed based on the variety of attribute tables using relational algebra such that the behavior profile is a separate table based on one entity and the entity's corresponding attributes (e.g., recorded activity). In this regard, the relational database objects and the behavior profile may be stored in the database 140. In one embodiment, the behavior profile may be stored in a cache of the database 140. In embodiments, a cache is a type of storage that allows for faster retrieval of data when a request is made. As such, when an analyst 170 wants to view and analyze behavior profiles via GUI 160, the behavior profiles are retrieved quickly via the web services 150. The web service 150 is an interface between the GUI 160 and the database 140 such that the behavior profiles may be viewed in a graphical format.

In one embodiment, when an analyst 170 requests to view an entity's behavior profile via GUI 160, the behavior profile for the specified entity may be generated at the time of the request and placed in the cache of the database 140. The behavior profile generated on demand may also be deleted on demand. In turn, size of the database 140 and/or cache is not a constraint on the system.

In one embodiment, and with reference now to FIG. 2, generating the behavior profile may include normalizing the data in the behavior profile. FIG. 2 illustrates an example of normalizing data in a behavior profile. Table 200 may be normalized such that the data is organized into three separate tables 202, 204, and 206. For example, table 202 may index the data by client number, table 204 may index the data by request number, and table 206 may index the data by encryption type. Due to the potential for large amounts of input data and the effect this would have on importing into persistent storage, normalization techniques are used to reduce storage requirements by avoiding the storage of duplicate items.

As discussed above, and with reference back to FIG. 1, the import services 130 may receive comparison data. The comparison data may be raw data (e.g., unprocessed data transmitted over one or more networks 110) that is received or data that is part of the behavior profile. For example, comparison data may include data from the behavior profile of the entity being identified for anomalous behavior. In another example, comparison data may include recorded activity data of the entity or suspect being watched for anomalous behavior. The date range used to create the comparison data may be configurable and may include a time slice that is before, after, or within the benchmark date range.

As discussed above, the import services 130 may determine whether the comparison data deviates from a pattern of behavior defined in the behavior profile. In one example, determining whether the comparison data deviates from a pattern of behavior defined in the behavior profile may include comparing the comparison data to the behavior profile and identifying as anomalous behavior a first portion of the comparison data that does not exist in the behavior profile. In one example, comparing the comparison data to the behavior profile may include overlaying the comparison data with the behavior profile to identify any differences. In another example, comparing the comparison data to the behavior profile may include identifying activities in the comparison data that are or are not in the behavior profile. In a further example, comparing the comparison data to the behavior profile may include analyzing attributes of the recorded activity such as access times, location data, information, page requests made, returned status, returned bytes, PKI status, page referrer URL, common access card information, login name, encryption information, weather data, etc. As such, any portion of the comparison data that does not exist in the behavior profile may be identified as anomalous behavior. Additionally, the lack of expected behavior in the comparison data (e.g., expected behavior that does exist in the behavior profile) may be identified as anomalous behavior.

In another example, determining whether the comparison data deviates from a pattern of behavior defined in the behavior profile may be based upon statistical analysis. In this example, statistical analysis may be performed to obtain minimum, maximum, average, and standard deviation values for daily activity. Statistical analysis may also be used to calculate bandwidth thresholds on arbitrary number based behavior attributes. Portions of the comparison data that lie outside a standard deviation of the behavior profile or exceed established thresholds are determined to deviate from the pattern of behavior defined in the behavior profile. As such, the portions of comparison data determined to deviate from the pattern of behavior defined in the behavior profile may be identified as anomalous behavior. Portions of comparison data determined to deviate from the pattern of behavior defined in the behavior profile may include an absence of behavior.

When the comparison data deviates from the pattern of behavior, the comparison data may be identified as anomalous behavior. When the comparison data is identified as anomalous behavior, a countermeasure may be performed. The countermeasure may include revoking the entity's credentials, denying the entity access to a resource, shutting down access to a port, denying access to a resource, and/or performing any other type of countermeasure known to the art. In turn, a threat to a resource, for example, may be prevented and/or stopped.

The import services 130 may further include at least one computer program for providing a report of the anomalous behavior. The report may be a suspect activity report and/or an interactive report. The suspect activity report may define criteria for suspect activity. For example, the suspect activity report may include a day of the week and report the criteria for suspect activity for that day of the week. The analyst 170 may view the report and identify an entity who meets the most criteria for suspect activity. The interactive report may define criteria for normal activity (e.g., the pattern of behavior defined in the behavior profile) and for suspect activity. The analyst 170 may compare the normal activity with the suspect activity to discover additional relationships and patterns. Interactive reports may also allow the analyst 170 to view the source data used generate the reports.

FIG. 3 illustrates a method 300 for identifying anomalous behavior of an entity according to one or more embodiments of the present disclosure. Method 300 begins at operation 302 in which raw data is received. For example, raw data may be received by the application server and/or the import services. In one example, the raw data is any data that can be tracked over a period of time (e.g., behavioral data and/or activity data). For example, the raw data may include weather data, recorded activities of an entity, data representing lights turning on and off, entry into any system requiring authorization, web service endpoints, mission role data, system transactions, resource access, etc. As such, any raw data communicated via a network may be processed and/or stored by the application servers. In one embodiment, the raw data may be in the form of weblog data. In one example, the weblog data may include at least one of IP address information, browsing history, download data, and time information.

Method 300 continues to operation 304 in which a behavior profile for an entity is generated based on the raw data. For example, the import services may generate a behavior profile for an entity based on the raw data. The behavior profile may define a pattern of behavior for the entity. In one embodiment, the behavior profile may be generated using any desirable amount of raw data. For example, the behavior profile may be generated based on a day of raw data, an hour of raw data, a week of raw data, a month of raw data, a year of raw data, etc. In another example, the amount of raw data used to generate the behavior profile may be based on the content of the data. For example, the content of the data may include the type of activity that has actually been recorded in the raw data. In this regard, the behavior profile may be generated for any date range supported by the raw data.

At operation 306, comparison data is received. The comparison data may be raw data that is received or data that is part of the behavior profile. For example, comparison data may include data from the behavior profile of the entity being identified for anomalous behavior. In another example, comparison data may include recorded activity data from raw data of the entity being identified for anomalous behavior. The date range used to create the comparison data may be configurable and may include a time slice that is before, after, or within the benchmark date range.

After comparison data is received, flow proceeds to operation 308 where it is determined whether the comparison data deviates from the pattern of expected behavior defined in the behavior profile. For example, the comparison data may be compared to the behavior profile and a first portion of the comparison data that does not exist in the behavior profile may be determined to deviate from the pattern of expected behavior as defined in the behavior profile. Comparison data that deviates from the pattern of expected behavior defined in the behavior profile may then be identified as anomalous behavior. In another example, statistical analysis may be used. In one example, statistical analysis may be performed to obtain minimum, maximum, average, and standard deviation values for daily activity. Portions of the comparison data that lie outside a standard deviation of the behavior profile are determined to deviate from the pattern of behavior defined in the behavior profile. In another example, statistical analysis may be used to calculate a bandwidth threshold of daily activity. Statistical analysis may be used to calculate a bandwidth threshold of daily activity. Portions of the comparison data that exceed the bandwidth threshold of the behavior profile are determined to deviate from the pattern of behavior defined in the behavior profile. As such, the portions of comparison data determined to deviate from the pattern of behavior defined in the behavior profile may be identified as anomalous behavior. Portions of comparison data determined to deviate from the pattern of behavior defined in the behavior profile may include an absence of behavior.

At operation 310, if the comparison data deviates from the pattern of behavior defined in the behavior profile, flow proceeds to operation 312 where the comparison data is identified as anomalous behavior. When the comparison data is identified as anomalous behavior, flow proceeds to operation 314 where a countermeasure is performed. If the comparison data does not deviate from the pattern of behavior defined in the behavior profile, the comparison data is identified as expected behavior and flow proceeds back to operation 306 where comparison data is received.

FIG. 4 illustrates a method 400 for generating a behavior profile for an entity based on raw data according to one or more embodiments of the present disclosure. In one embodiment, a method 400 begins at operation 402 in which the raw data is transformed into relational database objects. For example, the raw data may be organized into a variety of tables based on the attributes of the entity recorded activity.

At operation 404, the behavior profile may be constructed based on the variety of attribute tables using relational algebra such that the behavior profile is a separate table based on one entity and the entity's corresponding attributes (e.g., recorded activity). In this regard, the relational database objects and the behavior profile may be stored in the database 140. In one embodiment, the behavior profile may be stored in a cache for the database 140.

At operation 406, the data in the behavior profile is normalized. The data in the behavior profile may be stored in one large database table such that it is normalized into more than one smaller table. For example, a first smaller table may index the data by client number, a second smaller table may index the data by request number, and third larger table may index the data by encryption type. Due to the potential for large amounts of input data and the effect this would have on importing into persistent storage, normalization techniques are used to reduce storage requirements by avoiding the storage of duplicate items.

FIG. 5 illustrates a method 500 for determining whether comparison data deviates from the pattern of behavior defined in the behavior profile according to one or more embodiments of the present disclosure. In one embodiment, a method 500 begins at operation 502 in which comparison data is compared to the pattern of behavior defined in the behavior profile. Comparing the comparison data to the behavior profile may include overlaying the comparison data with the behavior profile to identify any differences. In another example, comparing the comparison data to the behavior profile may include identifying activities in the comparison data that are or are not in the behavior profile. In a further example, comparing the comparison data to the behavior profile may include analyzing attributes of the recorded activity such as access times, location data, client information, page requests made, returned status, returned bytes, PKI status, page referrer URL, common access card information, login name, encryption information, etc. After comparison data is compared to the behavior profile, flow proceeds to operation 504 where a first portion of the comparison data that does not exist in the behavior profile is identified as anomalous behavior. As such, any portion of the comparison data that does not exist in the behavior profile may be identified as anomalous behavior. Additionally, the lack of expected behavior in the comparison data (e.g., expected behavior that does exist in the behavior profile) may be identified as anomalous behavior. For example, expected behavior that exists in the behavior profile may include some action that a user always takes.

FIG. 6 illustrates a method 600 for performing operations after identifying comparison data as anomalous behavior according to one or more embodiments of the present disclosure. In one embodiment, a method 600 begins at operation 602 in which a report of the anomalous behavior is provided. The report may be received at web services 150 such that the report can be displayed by GUI 160. The report may be at least a suspect activity report and an interactive report. The suspect activity report may define criteria for suspect activity. For example, the suspect activity report may include a day of the week and report the criteria for suspect activity for that day of the week. The interactive report may define criteria for normal activity (e.g., the pattern of behavior defined in the behavior profile) and for suspect activity.

At operation 604, a countermeasure may be performed. The countermeasure may include at least one of revoking the entity's credentials, denying the entity access to a resource, shutting down access to a port, and denying access to the entity. In turn, a threat to a resource, for example, may be prevented and/or stopped.

FIG. 7 illustrates an example of suspect user behavior profiles shown via a graphical user interface according to one or more embodiments of the present disclosure. As shown in FIG. 7, a suspect page 605 may include a list of behavior profiles 606 that include suspect behavior and that are indexed by user name 607. Behavior profiles may be marked as suspect if recent activity of a user (e.g., comparison data) deviates from the expected behavior in the behavior profile. Additional information 608 (e.g., attributes) for each behavior profile may be shown such as daily page views, unique page views, hours spent, the days the page was viewed, sources (e.g., clients) used, common access cards used, encryption types, referrers, user agents, first appearance, and last appearance.

FIG. 8 illustrates an example of filtering suspect user profiles by categories via a graphical user interface according to one or more embodiments of the present disclosure. The suspect behavior profiles 606 may be filtered by one or more categories 609 (e.g., attributes). For example, as shown in FIG. 8, the suspect behavior profiles may be filtered by unique pages viewed 610, sources used 611, and common access cards used 612. In this example, only those behavior profiles that include a “hit” in each of the unique pages viewed 610, sources used 611, and common access cards used 612 categories 609 will continue to be shown on the graphical user interface. It is appreciated that the behavior profiles may be filtered by only one category 609, by all categories 609, or by any number of categories 609 desired. While specific information is illustrated and described with respect to FIG. 8, one of skill in the art will appreciate that other types of information may be gathered and or displayed without departing from the scope of the disclosure.

FIG. 9 illustrates an example of the unique page views category of a behavior profile via a graphical user interface according to one or more embodiments of the present disclosure. The unique page views category 610 shows the benchmark date range 613 and the comparison date range 614. In the exemplary embodiment, the benchmark date range 613 includes six months of data and the comparison date range 614 includes two days of data, however one of skill in the art will appreciate that other date ranges may be employed. The unique page views category 610 for the given behavior profile may include additional information 608 for the benchmark data and the comparison data such as daily page views, unique page views, hours spent, the days the page was viewed, sources (e.g., clients or devices) used, common access cards used, encryption types, referrers, user agents, first appearance, and last appearance. The unique page views category 610 further shows the URLs 615 of each unique page viewed for both the benchmark and comparison data. While specific information is illustrated and described with respect to FIG. 9, one of skill in the art will appreciate that other types of information may be gathered and or displayed without departing from the scope of the disclosure.

FIG. 10 illustrates an example of the sources category of the behavior profile via a graphical user interface according to one or more embodiments of the present disclosure. In the exemplary embodiment, the sources category 611 shows data for the same benchmark and comparison date ranges 613, 614 as that shown in FIG. 9. The sources category 611 also includes the same additional information 608 as that shown in FIG. 9, e.g., daily page views, unique page views, hours spent, the days the page was viewed, sources (e.g., clients) used, common access cards used, encryption types, referrers, user agents, first appearance, and last appearance. The sources category 611 further shows the different sources used 616 and the total number of page views 617 from each source for both the benchmark and comparison data.
